Correcting device for horizontal height of impression cylinder tooth pad of offset press

Abstract

The invention discloses a correcting device for the horizontal height of an impression cylinder tooth pad of an offset press. The correcting device comprises a locating base (4); and the locating base (4) has a circular bottom which is fit with the surface of the impression cylinder (6). The correcting device is characterized in that an dial indicator (2) for measuring the height of a tooth pad is set, the dial indicator (2) is fixed at the front end of a bracket (3); and the bracket (3) is matched with a sliding chute arranged on the base (4) so as to adjust the displacement of the dial indicator (2) along the direction perpendicular to the axial direction of the impression cylinder. The correcting device for the horizontal height of the impression cylinder tooth pad of the offset press, provided by the invention, overcomes the condition that when a caliper rule is used for measurement, due to the human factors, the measuring datum points placed by a hand are different to cause measurement errors, improves the measurement precision, reduces the measurement time and improves work efficiency.

Description

technical field [0001] The invention is a fast, convenient and accurate detection device for correcting the level of tooth pads of an impression cylinder of an offset printing machine in the printing industry. Background technique [0002] In the printing industry, during the transfer process of paper, that is, printing from one color to the next, the requirements for paper flatness and wrinkle-free handover on the tooth pad are very high. If the level of the tooth pad is different, it is necessary It will cause the transfer paper to appear wavy, resulting in inaccurate printing of front and rear colors. According to the requirements of the machine parameters of the offset printing machine, the horizontal height error of each group of offset printing cylinder tooth pads is less than or equal to 0.03mm (≤0.03mm), so that the paper can be transferred smoothly and accurately, ensuring that the printed products are full and clear in color. It can be said that the height error o...

Problems solved by technology

[0003] The existing measurement of the height error of the tooth pads uses common measuring tools in mechanical manufacturing and processing, such as depth vernier calipers or vernier calipers to measure the height of each tooth pad one by one. Since the reference points for measuring each tooth pad are different, and the detection is time-consuming and laborious, The error is large and cannot meet the requirements of machine precision.
